    摘要: A method of extraction of a key from a physical unclonable function using the states of cells of a volatile memory after a powering on, wherein: cells are read according to addresses stored in a non-volatile memory; an error-correction code corrects the read states; and, in case an error has been corrected, the address of the cell providing an erroneous state is replaced in the non-volatile memory with that of another cell providing the non-erroneous state.

    摘要: A device for the regeneration of a clock signal from an external serial bus includes a ring oscillator and counter. The ring oscillator provides n phases of a clock signal. Of these n phases, one phase is used as a reference and is applied to the counter. It is thus possible to count the number of entire reference clock signal periods between a first pulse and a second pulse received from the bus. In reading the state of the phases in the oscillator upon reception of the second pulse, a determination is made for a current phase corresponding to the phase delay between the reference clock signal and the second pulse of the bus. By using a regeneration device that also includes a ring oscillator and a counter, it is possible to regenerate the clock signal of the bus with high precision.

    摘要: A method of programming a row of antifuse memory cells includes breaking down at least N antifuse elements in the memory cells. The breakdown includes the application of a breakdown voltage to the anode of each antifuse element. The antifuse elements are broken down sequentially by groups of P antifuse elements, with P being less than N and at least equal to 1. The antifuse elements of a same group simultaneously receive the breakdown voltage. The breakdown of a next group of antifuse elements immediately takes place after the breakdown of a previous group of antifuse elements.
